Q2M3100MT - 100 Amp Circuit Breaker

Q2M3100MT - 100 Amp Circuit Breaker

If you're trying to match a Q2M3100MT circuit breaker, there are a few details you'll want to check beyond the part number. This is a 100-amp, 3-pole thermal-magnetic breaker with a10kA I.C. rating at 240VAC. It's a Q2MT type and has a non-interchangeable trip unit. One detail that can be especially helpful when identifying the correct breaker is the terminal setup. The Q2M3100MT has lug terminals on the line side and 1/4-20" studs on the load side. Size matters as well, particularly when you're working with existing or legacy electrical equipment. This breaker measures 6.5" high, 4.5" wide, and 3.13" deep. Before using it as a replacement, compare the electrical ratings, dimensions, pole count, trip arrangement, and connections with the breaker that's currently installed. When those requirements are met, the Q2M3100MT is a solid choice for maintaining the equipment's original form, fit, and function. It's built to last and intended for use within its stated ratings.
